The present invention pertains to a composition for treating a three-dimensional object precursor, the composition being used for separating a support material from the three-dimensional object precursor including a three dimensional object and said support material, wherein the composition for treating a three-dimensional object precursor contains water, and a water-soluble compound having a solubility parameter (SP value) of 8-13 (cal/cm3)1/2 as measured by the Fedors method. According to the present invention, a composition for treating a three-dimensional object precursor and capable of rapidly separating a support material; and a method for manufacturing a three-dimensional object via Fused Deposition Modeling using said composition for treating a three-dimensional object precursor, may be provided. 本发明是种三维物体前体处理剂组合物，其是用于从包含三维物体和支撑材料的三维物体前体中去除上述支撑材料的三维物体前体处理剂组合物，上述三维物体前体处理剂组合物含有水、以及基于Fedors法的溶解度参数(SP值)为8(cal/cm)以上且13(cal/cm)以下的水溶性化合物。根据本发明，可提供能够迅速去除支撑材料的三维物体前体处理剂组合物、以及基于使用了该三维物体前体处理剂组合物的热熔融层叠方式的三维物体制造方法。
